Abrasive slurry moving at speeds up to 1000 surface feet per minute process large parts or clusters of small parts on spindle mounted chucks. Centrifugal force spins the selected finishing media into a "form fitting grinding wheel" while slow rotation of the part in the mass assures uniform deburring and finishing of all surfaces. Delivers precision finishing of gears, bearing cages, splined shafts, pump rotors, jet compressor discs, jet blades and other complex parts.
